Description
Technical field
A kind of power system experimental rig is the utility model is related to, specifically a kind of SF6 density monitors calibration equipment.
Background technology
During carrying out sulphur hexafloride circuit breaker density monitor verification at the scene, there are a lot of density monitor verifications and connect
Unqualified problem caused by point is obstructed.After changing new density monitor, it is qualified again that old density monitor is tested again.Point
Analysis finds that the relay of this type is oil-filled density monitor, in running all the year round, due to never acting,
One layer of oil film is generated in the junction of relay.When being verified, because former density monitor checking table voltage is relatively low（Directly
Flow 12V）, oil film can not be punctured, electric current can not be by causing the obstructed phenomenon of contact.After relay is dismantled, due to shake
Dynamic, oil film is rinsed, and there have been the phenomenon of pass the test when testing again.
Cause《National grid 18 is counter to arrange》It is required that working site does not allow dismounting density monitor to be verified, therefore
Scene occurs that density monitor contact is obstructed, and the wrong diagnosis of pass the test can not be found in time again after replacing.To solve working
The wrong diagnosis problem of live sulfur hexafluoride density relay verification is, it is necessary to develop a kind of dedicated calibration apparatus, and convenient scene is to close
Spend the verification of relay.
The content of the invention
The utility model provides a kind of SF6 density monitors calibration equipment, simulates protective loop, being capable of quick accurate judgement
Whether density monitor contact can correctly act, for avoid the density monitor contact caused by the oil film obstructed and caused by by mistake
Judge and diagnosed in advance.
The technical scheme that the utility model is taken is：
A kind of SF6 density monitors calibration equipment, including verification casing, it is described verification casing be provided with red alarm lamp,
Yellow alarm lamp.The alarm contact connection of red alarm lamp, AC220V power supplys, SF6 density monitors, forms first and tests back
Road；The locking contact connection of yellow alarm lamp, AC220V power supplys, SF6 density monitors, forms the second test loop.
It is described verification wall box be provided with the first binding post 1., the second binding post 2., the 3rd binding post 3., the 4th
Binding post is 4.；First binding post 1., the second binding post 2. two contacts of alarm contact with SF6 density monitors respectively
Connection；3rd binding post 3., the 4th binding post 4. two contact portions of locking contact with SF6 density monitors respectively.
First binding post 1., the 3rd binding post 3. connect AC220V power line L ends；Second binding post 2.,
4. 4th binding post connects red alarm lamp one end, yellow alarm lamp one end respectively；The red alarm lamp other end, yellow alarm
The lamp other end connects AC220V power line N-terminals.
The red alarm lamp other end, the yellow alarm lamp other end pass through air switch QF connection AC220V power lines N
End.
The device also includes：AC220V power supplys, measurement circuit with plug are connected, when not testing, measurement circuit is rolled
It is placed in checking box body.
The verification casing is made for cleat insulator, sets a case lid thereon.
Using a kind of SF6 density monitors calibration equipment of the utility model, when can test at the scene, density relay is not dismantled
Device is verified.Particularly carry out doubtful density monitor contact it is obstructed in the case of, can connecting test line see that signal lamp is
It is no bright, such failure is easily excluded, wrong diagnosis caused by so as to avoid therefore.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model device；
Fig. 2 is the utility model device to test electrical schematic diagram.
Embodiment
As shown in Figure 1 and Figure 2, a kind of SF6 density monitors calibration equipment, including verification casing 1, it is described to verify on casing 1
Provided with red alarm lamp 2, yellow alarm lamp 3.
The alarm contact connection of red alarm lamp 2, AC220V power supplys, SF6 density monitors, forms the first test loop；
The locking contact connection of yellow alarm lamp 3, AC220V power supplys, SF6 density monitors, forms the second test loop.
Verification casing 1 side wall be provided with the first binding post 1., the second binding post 2., the 3rd binding post 3., the
Four binding posts are 4.；
First binding post is 1., alarm contact two contacts of second binding post 2. respectively with SF6 density monitors connect
Connect；
3rd binding post is 3., locking contact two contacts of the 4th binding post 4. respectively with SF6 density monitors connect
Connect.
First binding post 1., the 3rd binding post 3. connect AC220V power line L ends；
Second binding post 2., the 4th binding post 4. connect the one end of red alarm lamp 2, the one end of yellow alarm lamp 3 respectively；
The other end of red alarm lamp 2, the other end of yellow alarm lamp 3 connection AC220V power line N-terminals.
The other end of red alarm lamp 2, the other end of yellow alarm lamp 3 pass through air switch QF connection AC220V power lines
N-terminal.
The device also includes：Connect AC220V power supplys, measurement circuit 4 with plug, when not testing, measurement circuit volume 4
Rise and be placed in verification casing 1, avoid measurement circuit 4 from winding, link, be convenient for carrying.
